Version Downloads

LayoutInspectorV2-Pro is an Android Studio/Intellij plugin that allows Android developers to dump the view hierarchy. It is similar to the Legacy-Layout-LayoutInspector in some ways.

For convenience, LegacyLayoutInspector is abbreviated as LLI.


Preferences(Settings) > Plugins > Marketplace > Search and find "LayoutInspectorV2-Pro" > Install Plugin

Restart the IDE after installation.



You can find the plugin in the Tools menu.After the dump, LayoutInspectorV2-Pro generates a file with the .liv2 extension, just like the .li file.


Why Use LayoutInspectorV2-Pro?

The Google Android team removed the Legacy-LayoutInspector from Android Studio Bumblebee. If you are a fan of LLI, this plugin will be useful for you. Based on LLI, LayoutInspectorV2-Pro has made some improvements, including:

  1. Faster dump speed
  2. Easier selection of the view you want

The following section explains these improvements in detail.

Dump Speed

LLI provides two ProtocolVersions: ProtocolVersions.V1 and ProtocolVersions.V2. According to the source code, this feature was added in 2015.


LLI uses the V1 version by default to dump, but the V1 version is very slow. You may have seen a pop-up window warning of timeout.


Unfortunately, only internal Google engineers can use the V2 version. Therefore, LayoutInspectorV2-Pro uses the V2 version by default. I tested the dump speed of these two versions on my OnePlus 7 device with various numbers of views, and here are the results:

3000 views 4000 views 5000 views
ProtocolVersions.V1 (ms) 4101 5352 6577
ProtocolVersions.V2 (ms) 625 724 837

Easier selection

Many Android developers who use LLI may be confused by its default selection algorithm, which prioritizes the topmost view. However, in most cases, the sizes of areas should carry more weight when selecting a view.

Consider the following scenario: there are two views, A and B, and B is on top of A. If you click the A area in the image panel, LLI may not select A because B is larger and covers A.


With LayoutInspectorV2-Pro, the sizes of areas between A and B are compared, and A is selected because it is smaller than B. This approach ensures that the most appropriate view is selected.
